Bottle cap and method therefor

ABSTRACT

A closure assembly includes an inner cap with threading along an inner surface. A threading profile extends along an outer surface of an inner cap sidewall. An outer cap is coupled with the inner cap. The outer cap includes an outer cap sidewall extending along at least a portion of the inner cap sidewall, and the outer cap sidewall is substantially cylindrical and uniformly smooth along at least an exterior face. The outer cap sidewall is sized and shaped to conceal the threading profile. An annular rim of the outer cap extends from an open end of the outer cap, and the annular rim is inwardly bent toward the inner cap. In another example, the annular rim extends over the inner cap sidewall and couples the outer cap with the inner cap with an interference fit.

TECHNICAL FIELD

Closures for vessels and in particular closures for drinking vesselssuch as bottles.

BACKGROUND

Fluid containers, such as bottles, cans and the like are closed forstorage, transportation and the like with closures, including bottlecaps and corks. Corks, for instance, are deformable and pushed into theopenings of containers (e.g., wine bottles) to seal a liquid, such aswine, away from the atmosphere to prevent spoiling of the liquid. Onedisadvantage of a cork is that a cork will allow leaking if it isimproperly fitted in a bottle or if the cork prematurely dries andthereby shrinks and/or cracks in the bottle opening. Additionally, animproperly fitted cork or dried cork may allow premature spoiling of theliquid within, for instance, if the liquid is wine, exposure to theatmosphere will prematurely oxidize the wine. Another disadvantage withcorks is the difficulty of replacing them in a bottle. To obtain a tightseal, the cork must be placed over the bottle opening and forced intothe opening. Improper alignment of the cork with the opening orinsufficient pushing force prevent adequate resealing of the bottle andcan cause leakage and/or spoiling of the contents. Additionally, a corkwill sometimes impart its own taste to liquids, such as wine, and taintthe aroma and flavor of the liquids kept in a bottle.

In other examples, closure assemblies are used to seal containers. Onedisadvantage of many closure assemblies is the complex method ofcoupling an inner cap and an outer cap. Some examples of closureassemblies have features, such as threading, ratchet grooves and thelike, along the exterior of the inner cap and corresponding featuresalong the interior of the outer cap. The outer and inner caps arecoupled together by engaging the corresponding features together. Usingfeatures (e.g., threading) to couple the outer and inner caps requirestime consuming and expensive additional manufacturing steps to form thefeatures. Additionally, extra assembly is needed to engage the featuresof the inner cap with the threading of the outer cap. Further, formingsuch features sometimes roughens the exterior of the outer cap with theprofiles of the features and/or knurling needed for tooling to grasp theouter cap and form the threading. The profiles and/or knurling create arough and unappealing appearance for the outer cap exterior. Moreover,some closure examples roll a portion of the open end of a cap to form aring around the bottom of the closure. The ring extends from the cap andhas a diameter larger than the cap itself thereby further roughening theappearance of the cap exterior.

What is needed is a closure assembly that provides a container with atight and consistent seal that prevents leaking and spoiling ofcontents. What is further needed is a closure assembly with a smooth andaesthetically appealing exterior that is inexpensive and easy tomanufacture.

DESCRIPTION OF THE EMBODIMENTS

In the following detailed description, reference is made to theaccompanying drawings which form a part hereof, and in which is shown byway of illustration specific embodiments in which the invention may bepracticed. These embodiments are described in sufficient detail toenable those skilled in the art to practice the invention, and it is tobe understood that other embodiments may be utilized and that structuralchanges may be made without departing from the scope of the presentinvention. Therefore, the following detailed description is not to betaken in a limiting sense, and the scope of the present invention isdefined by the appended claims and their equivalents.

FIG. 1 shows one example of a closure assembly 100 coupled to acontainer 102. The container 102 includes, but is not limited to, aliquid containing vessel, such as a wine or liqueur bottle. In anotherexample, the container 102 includes a can, a jar and the like sized andshaped to hold contents (e.g., liquids, solids and the like). Thecontainer 102 includes, in yet another example, a neck 103. The closureassembly 100 is coupled with the neck 103 of the container 102. A neckring 105 extends at least part way around the neck 103. In one option,the neck ring 105 is made of the same material as the container 102 andintegral to the container 102. As shown in FIG. 1, the closure assembly100 has a substantially smooth sidewall 104. The smooth sidewall 104 ofthe closure assembly 100 continues the smooth profile of the container102 and provides an attractive appearance to the assembly 100 coupledwith the container 102. In another option, the smooth sidewall 104flushly mates with the neck ring 105 to provide a substantially smoothand continuous profile between the neck ring 105 and the closureassembly 100. Additionally, as described further below, the smoothsidewall 102 mates well with wraps, for instance, tamper proofing foils,shrink wraps and the like. The smooth sidewall 102 does not interferewith the application of the wrap to the container 102 or the closureassembly 100. The smooth sidewall 102 and the profile of the container102 assist in providing a corresponding attractive appearance for thewrap.

FIG. 2 shows one example of the closure assembly 100. The closureassembly 100 includes an outer cap 200 that at least partially surroundsan inner cap 202. The outer cap 200 is coupled to the inner cap 202 sorotation of the outer cap 200 (e.g., to rotate the assembly 100 relativeto the container 102) correspondingly rotates the inner cap 202. Theclosure assembly 100, optionally includes, but is not limited to,aluminum, steel and the like. In one example, the closure assembly 100includes tin-plated steel. In another example, the closure assembly 100includes tin-free steel.

FIG. 3 shows the inner cap 202 prior to coupling with the outer cap 200(FIG. 2). The inner cap 202 includes an inner cap sidewall 300 extendingbetween an inner cap lid 302 and an inner cap opening 304. The inner capsidewall 300 includes threading 306 extending along at least a portionof an inner surface 308 of the inner cap sidewall 300. The threading306, in one example, is sized and shaped to engage with correspondingthreading on the container 102 (FIG. 1) to seal the container 102 whenthe closure assembly 100 is coupled thereto. A threading profile 310,corresponding to the threading 306, extends along at least a portion ofan outer surface 312 of the inner cap sidewall 300. The threading 306 isformed, in one example, by a continuous threading process. The inner cap202 is interposed between male and female tooling that have toolingsurfaces sized and shaped to form the desired threading pattern on theinner cap 202. The female tooling closes around the inner cap 202 andthe male tooling and forms knurls around the inner cap lid 302. Theknurls assist the female tooling to grasp the inner cap 202 while themale tooling turns with respect to the cap 202. When turned, theprofiles of the male and female tooling deform the inner cap sidewall300 and thereby form the threading 306.

In another option, the inner cap 202 includes a liner 314. The inner cap202 is sized and shaped to receive the liner 314 adjacent to the innercap lid 302. In one example, the liner 314 has slightly more area thanthe area defined by the inner cap sidewall 300 and thereby engages withthe sidewall 300 by way of an interference fit. As shown in FIG. 3, thethreading 306 provides a surface for the liner 314 to rest upon once theliner 314 is positioned adjacent to the inner cap lid 302, in anotherexample. The threading 306 thereby retains the liner 314 within theinner cap 202. In still another example, the liner 314 is retainedwithin the inner cap 202 with an adhesive, a mechanical fitting and thelike.

In one option, the liner 314 includes, but is not limited to, SARANEX™ aregistered trademark of the Dow Chemical Company. In another option, theliner 314 includes at least one material (e.g. polymers and the like)configured to prevent the passage of gases, water vapor and aromas whenthe closure assembly 100 is coupled with the container 102 (FIG. 1). Theliner 314, in yet another option, includes a laminate having a layer ofSARANEX™ coupled with a layer of compressible foam membrane. The foammembrane allows the lip of the container 102 to deform the liner 314when the container 102 is coupled with the closure assembly 100.Deforming the liner 314 tightly seals the liner 314 against thecontainer 102 and substantially prevents the ingress of gases, watervapor and aromas around the liner 314.

In yet another option, the inner cap 202 is a stand-alone cap 202 thatacts as a closure assembly without the outer cap 200. The cap 202 issubstantially smooth at the juncture between the cap lid 302 and the capsidewall 300. For example, when the threading 306 and threading profile310 are formed the area between the threading profile 310 and the innercap lid 302 is substantially free of knurling. The tooling used to formthe threading 306 (described above) grasps the cap 202 as describedwithout forming pronounced knurls on the inner cap sidewall 300 or theinner cap lid 302.

As shown in FIG. 3, the cap 202 includes a blunt annular rim 316. Theblunt annular rim 316 extends from the cap sidewall 300 and issubstantially adjacent to the inner cap opening 304. The blunt annularrim 316 is outwardly bent and provides a blunt surface to easily handlethe cap 202. Additionally, the blunt annular rim 316 minimizes thepresence of burrs, snags and the like extending along the leading edge318 of the cap sidewall 300 by providing the blunt surface for handlinginstead of using the leading edge 318. Moreover, the blunt annular rim316 is free of curling toward the cap side wall 300. For instance, theannular rim 316 does not curl back over itself to form a ring around thecap 202.

Optionally, the blunt annular rim 316 is sized and shaped so at least aportion of the blunt annular rim profile, for instance, the leading edge318, is substantially flush with the profile of the neck ring 105 (FIG.1). The annular rim 316 and the neck ring 105 thereby provide a smoothcontinuous profile therebetween. As a result, the cap 202 smoothlytransitions into the container 102 (FIG. 1) to provide a smooth overallappearance for the container 102 and the cap 202. In another example,the annular rim 316 and the neck ring 105 cooperate to provide thesmooth continuous profile and facilitate positioning of a wrap (e.g.,wrap 700, described below) around at least portions of the cap 202 andthe neck 103 of the container 102. At least a portion of the bluntannular rim 316 and the neck ring 105 are visible through the wrap andat least the leading edge 318 and the neck ring 105 are substantiallyflush thereby presenting a smooth attractive appearance for the wrap,container 102 and the cap 202.

FIG. 4 shows the outer cap 200 including the outer cap sidewall 400extending between an outer cap lid 402 and an outer cap opening 404. Theouter cap sidewall 400 has an interior face 406 sized and shaped to beslightly larger than the outer surface 312 of the inner cap 202. Theouter cap 200 is thereby configured to slidably couple over thethreading profile 310. In one example, the outer cap 200 slides over thethreading profile 310 in a direction parallel to an inner cap verticalaxis 204 (FIG. 2). The outer cap 200 is moved over the inner cap 202(FIG. 3) until the inner cap lid 302 engages the outer cap lid 402. Theouter cap 200 is free of features, such as threading corresponding tothe threading profile 310 of the inner cap 200. Assembly of the innercap 200 and the outer cap 202 is expedited because there are nofeatures, such as threading, grooves and the like to mate between thecaps 200, 202 and rotation of one cap with respect to the other isthereby not needed (See FIG. 4).

The outer cap sidewall 400 has a substantially uniformly smooth exteriorface 408. As described above the outer cap 200 slides over the threadingprofile 310. The substantially smooth exterior face 408 conceals thethreading profile 310. The substantially smooth exterior face 408provides a smooth profile for the closure assembly 100 that isaesthetically appealing while the closure assembly 100 provides a sealfor the container 102. As described below, the substantially smoothexterior face 408 assists in providing a smooth appearance to wraps andthe like used to tamper proof the container 102 and the closure assembly100.

Referring again to FIG. 2, the inner cap 202 is coupled with the outercap 200. The inner cap 202 is engaged against the outer cap 200 so theinner cap lid 302 (FIG. 3) is engaged to the outer cap lid 402 (FIG. 4).As described above, the interior face 406 is free of features and theinner cap 202 slides into engagement with the outer cap 200 along theinner cap vertical axis 204. In one option, an adhesive 206 isinterposed between the inner cap lid 302 and the outer cap lid 402. Theadhesive 206 couples the inner cap 202 with the outer cap 200. In oneexample, the adhesive 206 includes, but is not limited to, an FDAapproved adhesive that provides a metal-to-metal bond. For instance, acyanoacrylate based adhesive including, but not limited to, 430 SUPERBONDER™ instant adhesive. SUPER BONDER™ is a registered trademark of theLoctite Corporation of Connecticut. In another example, the adhesive 206extends across only portions of the inner cap lid 302 and the outer caplid 402. The adhesive 206 extends across the inner cap lid 302 and theouter cap lid 402 and between portions of the inner cap sidewall 300 andthe outer cap sidewall 400, in yet another example.

As shown in FIG. 2, in another option, an annular rim 208 extends fromthe outer cap sidewall 400 around the outer cap opening 404. The outercap sidewall 400, in one example, includes the annular rim 208. Theannular rim 208 includes, but is not limited to, similar materials usedto form the outer cap 200 (e.g., aluminum, steel and the like). Theannular rim 208 is bent toward the inner cap 202 (e.g., the inner capsidewall 300). The bent annular rim 208 provides a blunt inwardlyextending surface that assists easy gripping of the closure assembly100. The closure assembly 100 is thereby easily handled during couplingwith the container 102 and after the assembly 100 is uncoupled from thecontainer 102. Additionally, the bent annular rim 208 minimizes burrsand edges at the leading edge of the rim 208 (i.e., the edge closest tothe inner cap sidewall 300) because of the inward bend of the rim 208.The annular rim 208 extends over at least a portion of the inner capsidewall 300, in one example, as shown in FIG. 2. The innercircumference of the annular rim 208 is smaller than the circumferenceof the inner cap 202, in another example, and the annular rim 208creates an interference fit between the outer cap 200 and the inner cap202 thereby coupling the caps 200, 202. Optionally, a portion of theannular rim 208 extends over the inner cap sidewall 300 to create theinterference fit. In yet another example, the annular rim 208 extendsover at least a portion of the inner cap sidewall 300 and the rim 208 isengaged against the sidewall 300 to securely retain the inner cap 202within the outer cap 200. The bent annular rim 208 cooperates with theadhesive 206, in still another example, to couple the inner cap 202 withthe outer cap 200.

In another option, the annular rim 208 is bent at around the same timethe inner cap 202 is coupled with the outer cap 200. For instance,tooling is adapted to couple the inner cap 202 with the outer cap 200and adapted to engage the annular rim 208 and inwardly bend it asdescribed above. Coupling the caps 200, 202 and forming the bent annularrim 208 at the same time shortens manufacturing times and decreasescosts by performing two operations at a single time.

FIG. 5 shows one example of the closure assembly 100 including an outercap 200 with printing 500A, B. The printing 500A is on the outer cap lid402 and the printing 500B is on the outer cap exterior face 408.Optionally, the closure assembly 100 includes at least one of printing500A or 500B. In another option, the printing 500A, B includes multipleor single features that are merged between the outer cap lid 402 and theexterior face 408. The printing 500A, B includes, but is not limited to,colored coatings (e.g., for at least a portion of the outer cap 200),printed on designs, labels, logos and the like. For example, the coloredcoatings include paints, polymers and the like configured to provide adifferent color than the base material of the outer cap 200. In anotherexample, the printing 500A, B includes a design, label or logo (e.g.,decorative artwork, winery emblems, company emblems, text, and thelike).

FIGS. 6A, B show another example of a closure assembly 100 withembossing 600. The embossing 600 extends from the outer cap lid 402. Inone option, as shown in FIG. 6B, the outer cap 200 is embossed and theinner cap 202 is free of embossing. The inner cap 202 is not embossedbecause it is substantially concealed by the outer cap 200. In anotheroption, both the outer and inner caps 200, 202 include embossing. Forinstance, the caps 200, 202 are embossed after coupling the outer cap200 with the inner cap 202. The embossing 600 includes, but is notlimited to, designs, labels, logos and the like. As described above withthe printing 500, the embossing 600 includes, for instance, decorativeartwork, winery emblems, company emblems, text, and the like. In anotherexample, the embossing 600 and printing 500A cooperate to provide anembossing 600 that includes the printing 500A.

FIG. 7 shows one example of the closure assembly 100 coupled with thecontainer 102. A wrap 700 is coupled between the closure assembly 100and the container 102. For instance, the wrap 700 at least partiallysurrounds a portion of the closure assembly 100 and the container 102.In one option, the wrap 700 includes, but is not limited to, foils,shrink wraps, plastic films and the like. The wrap 700, in anotheroption, serves as a tamper indication device (e.g., removal or damage tothe wrap 700 indicates tampering). In one example, the wrap 700 isslipped around the closure assembly 100 and the container 102 theassembly 100 is coupled with. Because the closure assembly 100 is freeof an outwardly curled ring and flushly mates with the neck ring 105,the wrap 700 has an inner circumference slightly larger than the closureassembly 100 to permit sliding of the wrap 700 over the closure assembly100 and the neck 103. The wrap 700 thereby uses less material and iseasier to couple around the closure assembly 100 and the neck 103. Forinstance, the wrap 700 does not snag on the closure assembly 100 or theneck ring 105.

As described above, in one option, the wrap 700 is a shrink wrap. Theshrink wrap is positioned around at least a portion of the closureassembly 100 and the neck 103 and heat is applied to shrink the wrap 700and couple it with the neck 103 and the assembly 100. In another option,the wrap 700 is a film or foil that is compressed and/or wrapped aroundthe closure assembly 100 and the neck 100. The profile of thesubstantially uniformly smooth exterior face 408 shows through the wrap700 and thereby presents an aesthetically appealing appearance.Additionally, the flush mating of the neck ring 10S and the closureassembly 100 shows through the wrap 700 to present a smooth andappealing profile across the neck ring 105 and the assembly 100.

FIG. 8 shows a method 800 for making a closure assembly. One example ofa closure assembly is assembly 100, shown in FIGS. 1-4 and referred tobelow. At 802, an inner cap 202 (FIG. 2) is formed. The inner cap 202includes threading 306 (FIG. 3) extending along the inner surface 308 ofthe inner cap sidewall 300. A threading profile 310 correspondinglyextends along the outer surface 312 of the inner cap sidewall 300. At804, the outer cap 200 is formed. The outer cap includes an outer capsidewall 400 (FIG. 4) that is substantially cylindrical and uniformlysmooth along at least an exterior face 408. At 806, the outer cap 200 iscoupled with the inner cap 202. As shown at 808, at least the threadingprofile 310 is concealed. In one example, the threading profile 310 isconcealed by the uniformly smooth exterior face 408 of the outer cap200. At 810, the annular rim 208 (FIG. 2) is bent toward the inner cap202. The annular rim 208 extends from an open end of the outer cap 200,for instance, the outer cap opening 404 (FIG. 4). In another example,the method 800 includes extending the annular ring 208 over the innercap sidewall 300.

Several options for the method 800 follow. In one option, the outer cap200 is embossed and the inner cap 202 is free of embossing. For example,the outer cap 200 is embossed prior to assembly with the inner cap 202.Coupling the outer cap 200 with the inner cap 202 occurs at around thesame time as bending the annular rim 208 toward the inner cap 202, inanother option. In yet another option, coupling the outer cap 200 withthe inner cap 202 includes adhering the caps 200, 202, for instance withan adhesive, such as adhesive 206.

CONCLUSION

Using examples described above, a number of advantages are realized. Oneadvantage includes a closure assembly that provides a tight andconsistent seal with a container. The closure assembly substantiallyprevents spoiling of a liquid, such as wine, because of prematureoxidation. Additionally, the closure assembly substantially preventsleaking of the container contents. Moreover, the closure assembly allowsfor easier resealing of a container by, for instance, screwing theclosure assembly onto the container. Further the closure assembly doesnot taint the contents of the container (e.g., wine) with the taste ofthe assembly, thereby substantially preventing alteration of the flavorand aroma of the contents.

Furthermore, the closure assembly is easy to manufacture and assemblebecause the outer cap sidewall moves over the threaded profile of theinner cap and the adhesive and/or the bent annular rim is used to couplethe inner and outer cap together. In one option, the bent annular rim isformed at the same time the inner cap is engaged to the outer cap,thereby further expediting manufacturing. Because the outer cap iscoupled to the inner cap with an adhesive and/or bending of the annularrim, expensive features such as mated threading, grooves, ratcheting andthe like are unnecessary to couple the inner and outer caps together.The bent annular rim provides a blunted surface around the opening ofthe closure assembly for easy coupling and removal of the assembly withthe container.

The outer cap conceals the threading profile of the inner cap andthereby provides a smooth aesthetically appealing appearance for theclosure assembly. The smooth cylindrical surface of the outer cap mateswell with tamper proofing foils, wraps and the like to provide a tamperproof and attractive seal to containers. Further, because the annularrim is inwardly bent the ridge does not alter the attractive appearanceof the closure assembly with the tamper proofing features describedabove because the closure assembly exterior is smooth.

In another option, the outer cap is personalized with different colors,printed on designs, labels, logos and the like. Optionally, the outercap is embossed without correspondingly embossing the inner cap that issubstantially concealed. For example, the outer cap is embossed prior toassembly with the inner cap to leave the inner cap free of embossing.
